Jillian D'Onfro / Business Insider The ninth annual Digital NewFronts, a conference for marketers, is going on in New York City this week and next.

A bunch of companies like AOL and Refinery29 put on events during the conference, including YouTube, which always holds a giant bash called Brandcast where it trots out some of the site's biggest stars and tries to convince advertisers that they need to spend less money on TV, and more on digital video.

As one fellow attendee put it, of all the Newfronts parties, YouTube's is the one to attend.

YouTube star Lilly Singh led the event, and she too made a blunt bid to advertisers: "Gone are the days of 'testing' this platform. That is soooo 2013. YouTube is proven and the audience is here. I hope you are too."
